Harshita Stainless is a well-known Dubai, India-based manufacturer and supplier of high-grade stainless steel products. We aim to deliver dependable, high-performance stainless steel solutions catering to the industrial sector. Our specialty product, Stainless Steel 309H Tubing, is designed for strength, heat endurance, and corrosion resistance. Employed extensively in high-temperature conditions, our 309H tubing is recognized for having an extended service period and structural stability. Our primary concern at Harshita Stainless is customer satisfaction, providing affordable and long-lasting stainless steel tube solutions with international quality standards, catering to the requirements of various industries in India and around the globe.
Stainless Steel 309H Tube consists of about 22% of chromium and 12–15% of nickel along with trace amounts of carbon (0.04–0.10%), manganese, silicon, and iron. The alloy provides great resistance against oxidation and scaling at high temperatures. Mechanical properties are a tensile strength of 515–690 MPa, yield strength of 205 MPa, and elongation of 40% at 50 mm. The high carbon content improves high-temperature strength and creep resistance. These tubes have excellent performance in severe thermal and chemical conditions and find use in heat-intensive uses while maintaining durability, weldability, and long-term reliability.
